HENRY C. SPALDING, OF BROOKLYN, NEW YORK.

CURTAIN-FIXTURE.

Specication of Letters Patent No.

To all whom it may concer/n:

Be it known that I, HENRY C. SPALDING, of Brooklyn, Eastern district, in the county of Kings and State of New York, have invented certain new and Improved Devices for Curtain-Fixtures; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the let ters of reference marked thereon, in which- Figure 1, is a front view of my improvement. Fig. 2, is an end view of ditto. Fig. 3, is a sectional view of ditto looking from the left hand end. Fig. 4, is a view of the top part of ditto showing how the roller comes out. Figs. 5, 6, and 7 are views in detail of the hanger D full size. Figs. 8, 9 and 10 are views ofthe hanger E in detail full size. Figs. 11, 12, and 13, are views in detail of the rack G full size.

Similar letters of reference indicate corresponding parts in the several gures.

This invention relates to a new and improved manner of constructing or using the several parts necessary for holding and regulating window shades or curtains as will be presently shown and described.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.

i4, represents a frame on which the fixtures are secured so as to show their position and the mode of operation.

B, represents the roller to which the curtain O, is fastened.

D, and E, are hangers in which the roller B, is placed; they are each cast in one entire piece and their parts are arranged and used as follows; the hanger D, is furnished with a rim a, for supporting the roller B, it has also a bed plate b, by which it is fastened to the frame A, from the bed plate b, a flange 0, extends over and partially around the roller B, and connected at its outer end to the rim a., by the tie d, so as to hold it rmly in position.

The cord F, is wound around the roller B, so that it passes once around the lower and twice around the upper half thereof in such a manner, that the flange c, separates the two upper portions of the cord and thus prevents it froinchanging its place on the roller.

When the cord F, is pulled downwards in one direction the roller B, is forced by the combined action of the cord and iiange 23,047, dated February 22, 18'59.

c, against the shield or head E, which stops the endwise motion of the roller while the curtain continues to ascend till it is rolled up.

On unrolling the curtain by the reverse action of the cord the roller is moved endwise until it is arrested by the head g, of the hanger E; on striking this, the tendency of the roller is to climb the head till the top thereof is reached whence it would be .precipitated to the Hoor-this tendency is counteracted by the narrow rim f, which prevents the roller from climbing the head g, while it does not prevent the removal of the roller because of its end play which allows it to be lifted past the rim f, when forced toward the hanger D.

After lifting the roller above the wide rim L, of the hanger E it can then be brought forward clear of the hanger as illustrated in Fig. 4, and then dropped down, which act disengages the roller and cord from the hanger D.

Before replacing the roller in the hanger for use the cord F, should be wound once and a half around the roller at the end thereof; then place the end with the cord in the hanger D, in such a manner that the two upper port-ions of the cord shall be on different sides of the flange c, the other end of the roller can then be lifted into its place in the hanger E.

It will now be observed that the roller and curtain are not under control so that i they can be easily regulated and to this end the rack G, is introduced; it consists of a slotted plate i, furnished with ratchet teeth on its face and an oscillating hook shaped stud 1, which is notched in such a manner as to slide freely up and down in the slot of the plate z'.

I/Vhen the cord F, is placed in the hook of the stud y, and the stud is pressed gently downward it is engaged in the ratchet teeth of the plate z', and thus holds the cord at any required degree of tension enabling the operator to control the curtain at pleasure.

The cord can be detached from the hook by pulling it a little forward which disengages the stud from the teeth of the plate and allows it to rise so that the cord is slackened.

The advantage of these devices is in their simplicity durability and effectiveness in which it is believed they excel anything.

heretofore used for the same purposes.

Having described its construction and operation, what I claim as my invention and with the roller, the cord and the rack oondesire to secure by Letters Patent isstructed substantially as described and oper- 1.
